b .au fuv/wmrtimayjconcern! i Si Be it known that I, CHARLES H. Mimes,

` acitizen of lthe United States, residing at Buffalo, in the county of Erie Aand State of New York, have invented anew anduseful Carbureter, of whichl the specification.h v. n ,I This invention has reference. tonnprovements .in carbureters, and '-its object `is to following -is v*a provide-a means whereby air charged .with a'volatile,hydro-carbony to form an explosivelmixtureto be used particnlarlyin internailflcombustion engines, although not the carbureter, whereby va lsubstantially connecessarily conined to such use.- I

In accordance with the present' invention there is provideda casing or `container partly' Afilled l' with absorbent material and withinthe mass of .absorbent material there .is provided a oatfcbamber `controllingfan elongated needle lv alve working through an elongated valve seat introduced between the carbureteranda supplylof hydro-carbon liquid.. The absorbent material issol arranged as Ato be freely swept by air streams, 'the container beingfconnected at one end to the atmosphere through controllable means, and

)at the other end with the engine or other device to be supplied `with enriched air. yThe needle valve float is so arranged as to respond toivarying levels `of liquids within sta-nt level of'liquid ismaintained, and the ,absorbent material has at practically all times the same 4degree 'of saturation whereby the air traversing the carbureter will be brought 'into contactv witha bodyof lluid :from which' the air may be-equally charged ,under all-conditions. v

The yinvention will be best understood from a` consideration of thefollowi-ng detaileddescript'i'on 't'aken yin connection with thel accompanyingdrawings forming a part.'

Fig. 7 is ,a plan "view -ofthe structure shown in Gwith the needle valve in cross section. y l Referring t`o the drawings there is shown a. casing l which 'is lusually madelrectangu- 'lar in fo'rn1,"andis customarily longer than wide, although"anyparticular shape is ynot mandatory, but the elongatedformisto be 'preferredfv 1:" if" 7' In the bottom'portionrof thefinteriorof the casing "there is lodged 'a kplate'i preferablyv provided' with numerous perforations .3, but instead A'of theperforated' plate any other plate-like structure i'nay be employed whereby numerous passages through"the .plate are provided. In the' particulalf'instance, the plate f3^is formed with a marginal flange 4 supporting the plate a short distanceabove what constitutes the bottom .of the 'casing l when in use, and at vsuitable nterv'alsjthe'plate is; further supported by feetl 5, sotha't it will maintain its spaced relation with reference 4to the bottom of the casing. The plate 2 haslodged thereon a closely packed mass ofabs'orbent material 6, which is preferablyin the form ofzwicking with the strands upright, so that the' upper surface of the mass of lwicking is formed by the ends of the strands, the latter being cut o`li" transversely of' their length. The wickingmay be 4in long thin strips, and 'at 'l intervals the strips are separated by corruated perforated diaphragmsi? serving'to 'old` the fwicking in place and the perforations permitting free lflowfof liquid from one mass' of wicking to the other. Overlying the wicking are-rods 8 at suitableV intervalsI to hold the mass of wicking or absorbent material, together'with the diaphragms to the perforated plateor false bottom 2'.

- *In preferably'centralrelation to the mass of wickingv there iis. provided a tube 9 resting on and [securedto'theplate 2 at itsl lower end fand projeating*l abovethe'bottom of the wicking where it may be open. This tube 9 constitutes a float chamber, and lodged therein is a float 10 which may be in the form of a hollow closed structure snugly but freely -tting the tube 9, and when. the latter is circular the ioat is cylindrical, but if the tube 9 be of other shape in cross sec- -tion the shape of the float may conform thereto. Extending through the float and open 'at both ends are tubes 11l having no communication with the interior of the float, but permitting free flow of liquid from one V end ci the float to the other through the tubes. The loat may be constructed as shown in Figs. 6 and 7, where there is illustrated a float body 10a of smaller diameter than the tube 9, and carrying a peripheral series of tubes or rods 11a acting as spacers for the float, whereby it is centralized in the tube 9; lThis` leaves ample room for the .flow of liquid about the float, and while some .liquid may pass through the tubes 11*L they mayas well be solid rods, so `far as any necessity for the provision of the flow ot liquid therethrough is concerned, but are made tubular for lightness.

i. The top of the casing 1 carries a fitting 12 into which may be screwed a pipe 13, although so far as function is concerned t-he fitting 12 and pi e 13 may be integral, one with the other. Xtending axially through the litting 12' and pipe 13 is a passage 14 tapering from the end of the tting 12 remote from the pipe 13 to the end of the pipe 13 remote from the fitting 12, although, of course, the taper need not be as long as the combined length of the tting 12 and pipe 13. The fitting 12 is provided with ears 15 by means of which the said fitting may bel secured to the top of the casing 1 with the main portionl of thetitting extending into the casing andinto the upper open end of capillary, so that actual contact between the needle valve and the'walls of the passage 14 `is unnecessary to stop the flow of liquid, wherefore there 'is no liability of jamming the needle valve in its seat in the passage 14 lto thereby interfere with the ready response of the Iioat to lowering levels of liquid lwithin thecasing 1. This desirable condi.

tion is .brought about by having the needle valve greatly elongated and the taper portion of the passage 14 correspondingly `elongated,so that the ext-ent of the passage when reduced' to capillary cross section is suflicient to overcome thc effect of the head of liquid tending to iow past the valve. Y

.The pipe 13 carries a T fitting 17, one end of which is entered by a pipe 18 leading to a reservoir 19, which latter may be located at any convenient point, and at such a height that liquid therefrom will gravitate to thepipe 13. The reservoir 19 is made of sutiicient capacity to supply the casing 1 with liquid .for as long a period as may be desired without the necessity of replenishing the supply withfn the reservoir ,19. The other end ofthe 17 'from that entered by the pipe v18 carries a short pipe "20 which maybe vclosed by a cap 21, so that in case of necessity the cap 21 may be removed and the pipe 18 blown out. l

At one end of the casing 1 there is an opening 22 covered by a cap 23, confining a gauze sheet 24 over said opening. `The capf23 at the end remote from the opening 22 receivesone end of a pipe 25, which in turn carries a damper structure 26 of suitable form to admit air with more or less freedom to the pipe 25 in accordance with the will of an operator. The opening 22 is so arranged as to rise from about the levelof the ,top of the absorbent material 6 and is several times the area of the pipe 25, so that air entering the cap member 23 by way of the pipe 25 will spread out and be distributed into many fine streams by the gauze-24, and will then further spread outwithin the casing 1 over substantially the whole exposed upper surface of the closely packed mass of fibrous material 6. At the other end of the casing from the opening 22 is another openin 27 located higher than the opening 22, and t is opening 27 is covered b a cap member 2S outside 105 thecasing '1, t is cap 'member containing gauze layers 29 shown as two in number spaced apart,y but it will be understood that one gauze sheet may be employed instead of two. The cap member 28 1s connected by a 110 nipple 30 to a T coupling 31, which in turn is connected in line with` a nipple 30 to` a pipe 32 within which is .lodged a valve 33 preferably ofthe butterflyv type. Leading oii from the coupling 31 is a pipe 34 lwhich 115 in the installed apparatus communicates with the eX losion chamber of an engine, or v with any o her point of utilization of enriched air. The casing 1 is provided with a stop cock 35 at about the level of the top of 120 the wicking 6, and lending from the bottom of the casing is a branch valve 36, while con- 5 nected with the top of the casing is an inlet pipe 37 normally `closed by a screw plug 38.

If it be assumed that thecasing 1 contains 125 no liquid, then liquid from within'the' reservoir 19 may be permitted to {iow through the I pipe 18 to the pipe 13, and there being no liquid within the casing 1 the float 10 or 10 is inits lowermost position, wherefore the 130 valve stein-16 isso far removed from the walls of the passage 14 as to leave free pasi sagefor liquid reaching the pipe 13, and this liquid `thereupon flows intothe float chamber 9` andthrough or about the float 10 or 10 and fromthence through the perforations of the *plate 2 into the space between this plate a'iidthe'bottom of the casing. Such liquid spreads out fand as the level' f liquid rises above the bottom of thev plate 2,`the'1iqiiid will find its way into the wicking 6 until the latter becomes thoroughly saturated and finally; it will reach the top of the wicking and begin to flow oii' throughthe stop cock which is assumed to be' open. f The initial lilling may take -placerthrough the pipe 37 instead of in the manner stated. The rising" level `of liquid within the casing 1 causes a likefmovement of the ioat 10 until by the tiinetthe top ofthewicking is reached the needle valve 116 has entered the pipe 13 to' an extent to arrest further iiow of liquid there'- througli yinto the casing l. Suppose, now,

that the engine is put in operation, the suc` tion stroke ofthe engine causes` a condition of sub-atmospheric pressure in the pipe 34C, which condition is communicated to the interior ofthe casing 1 in the space or coni'- partment defined between the upper surface of the absorbent material and the top wall of thecasing, this space being substantially-unobstructed, `and there is, of course, at once established a tendency tovrelieve this condil l l l i l i l r tionby the inflow of air through the damper 26 to the pipe '25 and" from,v thence" through the gauze 24 and passage .that as the engineruns there are caused streams of air to move throughv the' casing1 4in the space above the absorbent. material, and these streams of air absorb tlie'liquid presented at theupper ends of the'libersof `the wicking.

or absorbent material, and because of the highly volatile nature of theliquid used thel air l'becomes charged with the volatilized liquidv kand by the `time the charged air reaches the gauzes29the mixture of air and volatilized hydro-carbon liquid is sufficiently intimateso that `after passing through the ganzes 29v which separate' the stream of' charged air into manyilne. streams the mixture assumes the desired intimacy. .The air so charged is too rich for use in ani explosion'engine, and, therefore, the mixtureis diluted by air introduced intovthe1 pipe 32 past the valve 33.

The casing 1 lielongated in the direction of the liow of air therethrough, so that the air remains in lcontact with the wet exposed surface of the wicking lfor a considerable time, thereby giving ample opportunity :tor

the charging of the fairv with'vo'latilizedV hydro-carbon. The constant presentation of fresh supplies ofaii' to the wicking within the interior of the casing ltendsuto deplete the wicking of liquid, and while ithe capil- 1 What is claimed lary attractiono the fibrous material causes a constant presentation o-f the" liquid atthe upper ends of'ltlie ibers of t-he wicking or fibrous material, the level'ofvl-iquid'within the -loat chamber 9 lowers until Jinally the float 10' or 10@ following suchlowering level ,withdraws the valve 16 from lthe passage 14 until the latter is sulicien'tly 'open to permit thcfhead of liquid in the reservoirA 19 to overcomo any holding back' of the `liquid due to 'capillary attraction andv liquid from: the'- G thoroughly' wet and to maintain atthe` upper ends ot' the bers a quantity' ofhydroi carbon liquid ample to supply the needs of the. engine.

Having once adjustedthe-device itremains to alargeextent automatic in a-ction,"al

though the varying atmospheric and other conditions may necessitate some adjustment of the dampers 26 and33. Itis to be ob served that the float chamber 9 is preferably located about midway of the length and lbreadth ofthe casing 1 so that liq'uid entering the chamber is readily distributedto"thel lower-edges of the wicking. l lThe device of the present invention is well` adapted yfor lexplosioi'i engines whether of the stationary type or mountedon vehicles, and since there is no free liquid-within the casing 1 that can splash abou-t,"the shocks `and, jars towhich the device is.' subjected upon a vehicle`like anautomobile has no detrimental effect whatsoever tothe action of the device.
